AB  - In this study we defined model indicators of different muscle force characteristics while performing motor task: hand grip, by using isometric dynamometry method. The sample included 33 examinees (16 males, and 17 females) all students of Criminalistic-police academy, Belgrade, chosen randomly from the I year students of academic studies. The measured space was defined in relation to three aspects of muscle force dimensions: the aspect of muscle force (absolute value expressed in N, relative value expressed in N/kg BM and relativized value expressed in % out of Fmax), time aspect of expressing the given force percentage (time of endurance with 80, 50 and 30% out of Fmax, expressed in seconds) and mathematical models defined as different dependencies of expressed force characteristic as a function of time: Faps vs time, F% vs time i Frel vs time. The results show that by using mathematical modeling method, the measuring space is described by precision at the level of prediction from 99.97 % (in dependence F% vs time, girls, left hand) to 91.86% (in dependence F% vs time, man, right hand). However, for defining model indicators from the aspects of measured contractility capacity and for calculating the criteria indicators in young and healthy population it is necessary to repeat the measuring in the greater number of examinees.
AB  - U istraživanju je izvršeno definisanje modelnih pokazatelja različitih karakteristika ispoljavanja mišićne sile kod motoričkog zadatka - stisak šake, primenom metode izometrijske dinamometrije. Uzorak je bio sastavljen od 33 ispitanika (16 muškog i 17 ženskog pola) koji su činili studenti Kriminalističko-policijske akademije u Beogradu, izabrani kao slučajni uzorak studenata I godine akademskih studija. Ispitivani (mereni) prostor je definisan u odnosu na tri aspekta analize mišićne sile i to: aspekt mišićne sile (apsolutne vrednosti izražene u N, relativne vrednosti izražene u N/kg TM i relativizovane vrednosti izražene u % od Fmax), vremenski aspekt ispoljavanja datog procenta sile (vreme izdržaja na 80%, 50% i 30% od Fmax, izraženo u sekundama) i matematički modeli definisani kao različite zavisnosti ispoljene karakteristike sile u funkciji vremena i to: Faps vs time, F% vs time i Frel vs time. Rezultati su pokazali da je primenom metode matematičkog modelovanja prostor merenja opisan preciznošću na nivou predikcije od 99.99% (kod zavisnosti F% vs time devojke leva šaka) do 93.40% (kod zavisnosti F% vs time muškarci desna šaka). U svrhu definisanja finalnih modelskih pokazatelja merene kontraktilne sposobnosti i izračunavanja kriterijumskih pokazatelja za mladu i zdravu populaciju potrebno je ponoviti merenje na reprezentativnom broju ispitanika.
